Application filed December 1912. Serial No, 737,457;

To all whom it may concern Beit known. that I, EDwAnn Hnsrmes BIcKroRn, a. subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontar1o, 1n the,

Dominion of. Canada, have invented certain new and useful lmprovements in Motor-Car- Heating Devices, described in the following specification and illustrated in the accompanying drawings.

The principal features of the present 1nvention consist'in the novel construction and arrangement of parts, whereby a supply of warm airis directed to the interior of the car.

The objects of the invention are to render motoring in cold weather more comfortable by providing a supply of warm air to the interior of the car, utilizing the heat generated by the engine to the best advantage and 5 to devise a simple and inexpensive equipment which may be readily placed' in any car without interfering with or altering the mechanical equipment of the car.

In the drawings, Figure 1 is a perspective view of a motor car showing my device installed therein. Fig. 2 is a detail perspective view of my equipment assembled, showing the exhaust pipe from the engine and a portion of the engine bed and car frame, a portion of the engine being shown in dotted lines. Fig. 3 is a sectional elevational view of the equipment. Fig. 4 is a cross sectlonalview through the register for the rear of the car and the hot air pipe. Fig. 5 is a perspective detail of the front length of the hot air conduit showing the longitudinal edges separated ready for placing around the engine exhaust pipe.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the sloping foot board in the front compartment of the car. 2 is the engine bed or an extension therefrom extending rearwardly beneath said foot board and across the car.

3 is a plate in the form of a register or grille, forming a portion of the sloping foot board, and preferably extending across the car and resting at the ends upon the side sills4.

5 is a baffle plate, preferably formed intcgral with the plate 3, extending down,- wardly from said plate and fitting close to the engine bed 2 or its extension and closing {the Sp between th car body and said bed- The baflfle plate 5 is formed. with its lower ed'ge, shaped to any suitable contour to fit laroundi any portions of the engine bed or parts carried thereon. The engine chamber lin'closed' by the hood, engine bed and forgtpreferably slopes forwardly and downwardly from the register 3, directs the air [entering the engine chamber upwardly through the grille, where the driver places his feet. The-air is heated by contact with 3 the engine and particularly the exhaustpipe :which when the engine is running becomes very hot and a constant supply. of warm air is directed into the forward portion of the jcar beneath the robe or cover worn by the fdriver or occupants of the front seat. 6 is a. slot in the baffle plate 5 through Ewhich the exhaust pipe 7 of the engine ex- Qtends. The exhaust pipe in most cars is vraised above the engine bed consequently the %slot 6 leaves an opening below the baffie, 0r fif the construction of the car permits, the opening may be above the pipe.

Sis a plate pivotally connected to the bafiie at one side of" the slot 6 and adapted to close the said. slot, said plate having a suitable lever extension 9 projecting upwardly through, a slot in the grille by means of which the plate may be swung to open. or close the slot to allow or arrest the flow of air therethrough. p

10 are hook shaped lugs formed on the rear side of the bafiie 5 adjacent to the slot 6.

11 is a sleeve of sheet metal adapted to shaped edges 12 adapted to lock together. The sleeve is so constructed that it may be sprung open and, placed around the exhaust pipe and the hooked edges are then brought together and locked. The sleeve 11 is preferably formed in two sections the front section 13 being formed to fit snugly against the rear of the bafile 5 and preferably having the hook shaped lugs 10. The rear sleeve section 14 fits'over' the rear end of the front section 13. and at the rear end abuts the mufiler 1.5. i

16 is a sheet metal box open at thetop and arranged in an opening in the floor of the rear. compartment of the carand having a Patented} Oct. 20, 1914.

award portion of the car body is thus closed i.at'the rear side and the baffle plate 5 which encircle the exhaust pipe at the rear of the baffle plate and formed with reverse hook an outwardly turned flanged edge to engage tion of the moving air flows through the slot around the engine exhaust pipe and is conducted the full length of said exhaust pipe within the sleeve 11 and becoming thoroughly heated it flows through the air duct 17, box 16 and register 18, thus heating the rear compartment.

The equipment herein described is very simple and inexpensive and may be placed in any carin a few minutes. A portion of the ordinary foot board is lifted out and the grille 3 is dropped into place the sleeve sec-' tions being thenslipped over the exhaust pipe and the box 16 is fitted into an opening cut in the floor of the rear section of the car. .One end of the air duct 17 is preferably secured to the sleeve and the other end is then inserted into the opening in the side of the box and the flanges spread'out. The register is then dropped into place and the equipment is complete. 1

The sleeve encircling the exhaust pipe is formed in two lengths in order to facilitate the placing of same and also to allow of any slight adjustment in length which may be necessary in order that the front end may fit snugly against the baffle plate and the rear end abut the muilier. The sleeve when fitted snugly into place will not rattle or be objectionable in any Way and may be taken off or replaced in a few minutes.

I am aware that .various means have been devised for supplying heated air to the interior of motor cars, the air being heated by contact with the engine or exhaust pipe and I do not make any claim broadly to the principle involved but I do claim certain features of construction which enable the heating of a motor car in a very simple and inexpensive manner.

What I claim as my invention is 1. In a motor car heating device, the combination with the engine, exhaust pipe, and car body, of a grille arranged in the sloping foot board of the car body and having a downwardly project ing bafiie member which extends around the enginecxhaust pipe and close to the engine bed throttling the flow of air around the engine and exhaust pipe and directing the heated air upwardly through the grille.

2. In a motor car heating device, the combination with the engine, exhaust pipe, and car body, of a grille arranged in the foot board of the car body, a battle extending downwardly from said grille and directing through said grille, said bafiie havin a current of air upwardly therethrough,

said bafiie having an opening through which the exhaust pipe of the engine extends, a sleeve encircling said exhaust pipe and extending rearwardly from said bafiie and forming an air duct communicating with the. opening through said battle, a suitable register placed in the rear compartment of the car, and an air duct leading from said sleeve and directing a supply of warm air to said register.

3. In a motor car heating device, the combination with the engine, exhaust pipe, and "car body, of a grille arranged in the foot board of the car body, a bafiie closing the space between the car body and the engine .bed and directing a current of air upwardly through said grille, "said bafile having an opening therethrough through which the exhaust pipe of the engine extends, asleeve encircling said exhaust pipe and extending rearwardly from said baflie and forming an air duct communicating with the opening through said baflle, a suitable register placed in the rear compartment of the car, an air duct leading from said sleeve aind directing a supply of warma1r to saidiregister, and a v damper plate adapted to be "moved across'I the opening in said baffle plate to check the flow of air through said sleeve.
